Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

The chemical degradation of normal paraffin hydrocarbon (NPH) diluents both in the pure state and mixed with 30% tributyl phosphate (TBP) was investigated in a series of experiments. The results show that degradation of NPH in the TBP-NPH-HNO3 system is consistent with the active chemical agent being a radical-like nitrogen dioxide (NO2) molecule, not HNO3 as such. Spectrophotometric, gas chromatographic, mass spectrographic, and titrimet-ric methods were used to identify the degradation products, which included alkane nitro and nitrite compounds, alcohols, unsaturated alcohols, nitro alcohols, nitro alkenes, ketones, and carboxylic acids. The degradation rate was found to increase with increases in the HNO3 concentration and the temperature. The rate was decreased by argon sparging to remove NO2 and by the addition of butanol, which probably acts as a NO2 scavenger.
